4-6 Making measurements

Important :
The following effect will be noted with all field strength meters :
If move the sensor quickly, excessive field strength values will be
displayed which do not reflect the actual field conditions. This effect is
caused by electrostatic charges.
Recommendation :
Hold the meter steady during the measurement.
4-6-1 Short-term measurements
Application :
Use either the "Instantaneous" or the "Max. instantaneous" mode, if
the characteristics and orientation of the field are unknown when
entering an area exposed to electromagnetic radiation.
Procedure
1. Hold the meter at arm's length.
2. Make several measurements at various locations around your work
place or the interested areas as described above. This is particularly
important if the field conditions are unknown.
3. Pay special attention to measuring the vicinity of possible radiation
sources. Apart from active sources, those components connected to a
source may also act as radiators. For example, the cables used in
diathermy equipment may also radiate electromagnetic energy. Note
that metallic objects within the field may locally concentrate or amplify
the field from a distant source.
